Most modern RF power amplifiers are built from legacy analog circuits. Typically, such circuits are produced in multi-component modules and in costly, low-volume semiconductor processes like Gallium ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

Important efficiency requirements exist on both the handset and the base-station sides of the telecom world. In handsets, efficiency directly translates into battery life. By increasing cell-phone ...

Single-cell lithium-ion batteries traditionallyhave powered RF (radio-frequency) linearpower amplifiers in cell phones. Althoughthe use of these linear power amplifiers canhelp to meet the ...
